A 56-year-old female patient with left breast cancer presented at our hospital. Preoperative CT scan showed an isolated bilateral pectoralis major muscle defect and abnormal muscle originating from the entire sternum and inserting in the lower ribs and rectus sheath. Total mastectomy and axillary lymph node dissection were performed. We believe that this case is unique and that others like it have never been reported. If there is a defect in the pectoralis major muscle, reconstructive surgery with a tissue expander is contraindicated. Therefore, preoperative evaluation of the chest wall musculature on imaging is recommended.
一名56岁的左乳腺癌女性患者到我院就诊。术前CT扫描显示双侧胸大肌孤立性缺损，以及一块起源于整个胸骨、止于下肋和腹直肌鞘的异常肌肉。行全乳切除术和腋窝淋巴结清扫术。我们认为该病例独特，此前未见类似病例报道。如果胸大肌存在缺损，禁忌使用组织扩张器进行重建手术。因此，建议术前通过影像学对胸壁肌肉组织进行评估。
